Underground drinking water quality evaluation method

The invention provides an underground drinking water quality evaluation method, and belongs to the technical field of drinking water grade evaluation. The invention provides an underground drinking water quality evaluation method. The method comprises the following steps: (1) evaluation parameter selection; (2) establishing upper and lower limit threshold concentrations of water quality parameters; (3) calculating upper and lower limit threshold ranges; (4) optimizing the water quality parameter upper limit threshold concentration; (5) sub-index calculation; and (6) calculating a comprehensive index, and obtaining a water quality evaluation standard according to the comprehensive index. According to the method, the influence caused by too high or too low chemical parameter concentration of the water quality is fully considered on the basis of evaluating the underground drinking water, and the evaluation standard of the underground drinking water is perfected. 本发明提供了一种地下饮用水水质评价方法，属于饮用水等级评价技术领域。本发明提供的地下饮用水水质评价方
